The Problem:
When running npx react-native run-ios on an M1 Mac with React Native 0.71.5, Cocoapods 1.11.3, Node 18.15.0, Xcode 14.3, and macOS 13.3, the build fails with the error CompileC /Users/username/Library/Developer/Xcode/DerivedData/AwesomeProject-ctnixtnnzajiwuhfvbyaxljew/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/React-Codegen.build/Objects-normal/arm64/FBReactNativeSpec-generated.o /Users/username/Documents/testing/AwesomeProject/ios/build/generated/ios/FBReactNativeSpec/FBReactNativeSpec-generated.mm normal arm64 objective-c++ com.apple.compilers.llvm.clang.1_0.compiler (in target 'React-Codegen' from project 'Pods') (1 failure).
The Solutions:
Solution 2: Update iOS Deployment Target
To resolve the build failure, navigate to the Pods folder in Xcode and select React-Codegen under Build Settings. Update the iOS Deployment Target to iOS 12.4 or a supported version. This should address the compatibility issue and allow the build to complete successfully.
Solution 3:
Changing the minimum ios version of ReactCodegen inside Xcode targets to 12.0 or greater can solve this issue.
